Is it possible to do Hardware isolation of cortex-m3 from xC

[ippisl]

Let's assume the worst case : a malware program have got control over all the xcores in the xmos-xa(cortex-m3) device.

Another option - they've got control of every xmos xcore except the one dedicated to the AES.

Is it possible to program the device in such a way , so that this malware cannot get control over the cortex-m3, none of it's hardware peripherals , none of it's memory and none of i/o pins dedicated to it ? In other words - i know that   a certain functionality of my device is fully protected ?

Thanks.
